Zhang Qiru returned to the bar, and many people had already rested. Because the bar is open all night, it is quite lively. Zhang Qiru was lying on the bed, tossing and turning a little unable to sleep, he had been thinking about the matter of antivenom, as for the evolution of zombies, he had long been thrown aside, and what he was most worried about was that no one other than himself, Zhang Qidao and Zhao Yun could resist the virus, so he usually wouldn't let others take risks. Now that there is a safe solution to this problem, if the antivenom is really useful, then it will be considered a big problem for Zhang Qiru.

Zhang Qiru feels that it has been nearly a year since the end of the world, and the zombies have been constantly changing, from being very weak at the beginning, to now they are constantly getting stronger, as if they have been resisting the continuous development of human beings, and no one can help anyone, but it is difficult to say whether the zombies will be ahead of humans in the future, so Zhang Qiru is not thinking more about how to defeat the zombies, but how to keep the last fire of mankind in the last days.

The next day, Zhang Qiru woke up after only four hours of sleep and received a call from the governor.

"Come to the institute!" The Governor said.

Zhang Qiru hung up the phone, took Li Xiaorou and a few people straight to the research institute, and on the way Zhang Qiru briefly talked about the antivenom. In the research institute, the governor, Xiao Huang and Bai Chunyu are all there, waiting for Zhang Qiru and them.

"Uncle, what's so in a hurry?" Zhang Qiru asked.

"Listen to what Xiaoyu has to say!" The Governor said.

"Zhang Qiru, you already know about the antivenom, right?" Bai Chunyu asked.

"yes, just got it." Zhang Qiru replied.

"Just last night, I discovered something while researching antivenom." Bai Chunyu said, with a serious expression: "The secret about the virus!" ”

"You say!" Zhang Qiru didn't have to think about it, Bai Chunyu should have discovered a very remarkable secret.

"When I was testing the effectiveness of the antivenom, I found a piece of DNA in the virus, which was a human DNA fragment, I thought it was a mistake, and then I repeated the test, and it was indeed a human DNA fragment." Bai Chunyu said.

"Don't say it so professionally, I don't understand it......" Zhang Qiru said helplessly.

"I think what she means is that the virus originally came from humans...... "Li Xiaorou is also a doctor and knows a little."

"Yes, the probability that this piece of DNA was added later is very low, because the replication code of the virus is a complete DNA strand, similar to that of higher animals, but the sequence is different. However, some of these fragments are indeed human-like, and human-specific. Bai Chunyu said.

"Is it possible a coincidence?" Zhang Qiru asked.

"Probability-wise, it's about one in a hundred trillion, what do you think?" Bai Chunyu asked rhetorically.

"So viruses evolved from the human body?" Zhang Qiru asked.

"Likely, and we have an even worse inference." Bai Chunyu Road.

"What?" Zhang Qiru said.

"This is not a virus, or it was not originally a virus, but the tissue or cell of an unknown humanoid organism that was later discovered and studied. This unknown human may be much stronger than the current human being, not only in the body, but also in the intelligence, so some people have crooked ideas, but they can't control this virus, which leads to the disaster. Bai Chunyu said.

"And then?" Zhang Qiru asked.

"If that's the case, I think the end of zombie evolution should be the reappearance of that unknown humanoid creature to take the place of the current human." Bai Chunyu said.

When Zhang Qiru and others heard this, their hearts sank, and sure enough, the virus was not as simple as they imagined.

Of course, this is just speculation. I've seen your video to the Governor, viruses can control organisms to evolve in a better direction, this can't be controlled. It's not that zombies are smart, it's that the power of the virus is far from what we know, and it may control zombies to evolve in a direction that can defeat humans in order to eventually replace humans. Bai Chunyu continued.

"Does the antivenom work?" Zhang Qiru asked.

"Absolutely! However, this serum has a drawback, that is, it can only be concocted with the blood of the kind of zombie you brought back, otherwise it can't be made. Bai Chunyu said.

"Are there any side effects?" Zhang Qiru asked again.

"Didn't you give it to them?" Bai Chunyu asked in surprise.

"Of course not!" Zhang Qiru said.

"Isn't that a quick use, waiting to be robbed?" Bai Chunyu rolled his eyes and said.

"Didn't you say you wanted to observe?" Zhang Qiru said.

"I just said casually, why take it so seriously? Don't worry, no problem. I've been studying this question for a long time, the antibodies produced by absolute immunity can digest the virus, and the antibodies produced by complete immunity like you can forcibly interrupt the infection of the virus to cells, and the blood of special zombies can return the virus to its original state, so you don't have to worry about the mutation of the virus. Bai Chunyu said.

"Why didn't you say it earlier, I thought it wouldn't work!" Zhang Qiru said.

"Well, don't you believe me like that? I've been studying with you for a long time! Bai Chunyu said.

"Alright, alright! You're not just here for us, aren't you? Zhang Qiru asked.

"Of course! Didn't I just say it, now this antivenom has a drawback, that is, it must be the blood of special zombies, but we have also encountered special zombies, not only is it difficult to catch, but it is a matter of whether we can run away, so it is very unrealistic to use special zombies to create viruses in batches, so we can only find another way. Bai Chunyu said.

"Is there anything else that can be replaced?" Zhang Qiru asked.

"High-level zombies! The more high-level zombies, the more advanced evolution viruses exist in their bodies, and the reason why special zombies are powerful is nothing more than that the virus evolution is advanced enough, and the antivenom serum also uses this point, so it is okay to have enough high-level zombie corpses. Bai Chunyu said.

"Is it okay for a licker?" Zhang Qiru asked.

"It's too low, the lowest is the level of a tyrant! No matter how low it is, there is basically no possibility of extraction, because the amount is too small. Moreover, even at the level of a tyrant, I think it would take about ten antivenoms to make one! The Giant Licker should be better than the Tyrant, but not by much. Bai Chunyu said.

"I'm ...... Can the Scaly Demon reach one to one? Zhang Qiru asked.

"Well, it should be possible, after all, it's close to the level of special zombies." Bai Chunyu replied.

"Looks like we've got a new business?" Zhang Qiru said with a smile.

"Well, that's why I'm here for you. Starting tomorrow, the government will buy high-grade zombie corpses and then go all out to make antivenom! The Governor said.

"Okay...... That, uncle, will we also be used for research in the future? Zhang Qiru asked suddenly.

"Haha, don't worry, human blood can still be replicated indefinitely, and you don't need to donate blood regularly!" The Governor laughed.
